Description

Automobile part casting stretching die high in production efficiency

Technical Field

The utility model relates to a parts machining mould technical field, in particular to tensile mould of auto parts foundry goods that production efficiency is high.

Background

The existing stamping products in automobile parts need to achieve high strength, and the shapes of the products are usually complex. Meanwhile, due to the fact that the dimensional tolerance of the workpiece is very small in a specific matching relation, the range difference of 0.5mm is reserved at the position of an assembly hole, and the range difference of 0.5mm is reserved on the special side line profile. The molding surface of the product adopts the traditional molding mode and needs more working procedures and has scratch phenomenon.

Therefore, it is necessary to provide a new drawing die for automobile part castings with high production efficiency to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tensile mould of auto parts foundry goods that production efficiency is high realizes the one-step tensile shaping mode that targets in place, improves work efficiency.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a tensile mould of auto parts foundry goods that production efficiency is high, its including be used for tensile in-process product fashioned die, with the terrace die that the die matches, with the die holder that the terrace die is fixed, set up and be in just be equipped with the blank holder of locating piece on the die holder.

Further, the positioning block is used for positioning a product.

Furthermore, a mandril hole is formed in the lower die base.

Furthermore, the blank holder is arranged on the lower die holder and sleeved on the periphery of the male die, can move up and down under the action of the ejector rod of the oil press, can bear the pressing force in the stretching process, and is uniform in pressure and smooth in material feeding.

Furthermore, the female die acts on the blank holder in the downward movement process, and the formed product is clamped in the middle.

The utility model relates to a tensile mould of auto parts foundry goods that production efficiency is high's beneficial effect is, can one shot stretch forming, prevents to produce the surface production mar of part to great improvement work efficiency.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a schematic structural view of an efficient drawing mold for automobile parts castings;

FIG. 2 is a schematic view of the connection structure between the lower die holder and the fixed block of the high-production-efficiency automobile part casting drawing die of the present invention;

in the figure: 1. the die comprises a female die, 2 a male die, 3 a blank holder, 4 a lower die holder and 5 a positioning block.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention.

Example (b):

referring to fig. 1-2, the drawing die for the automobile part casting with high production efficiency comprises a female die 1 for product forming in a drawing process, a male die 2 matched with the female die 1, a lower die holder 4 fixed with the male die 2, and a blank holder 3 arranged on the lower die holder 4 and provided with a positioning block 5.

The female die 1 is used for forming a product in the stretching process, the female die 1 can extrude the blank holder 3 to generate a pressing force in the downward movement process, the blank holder 3 is finally matched with the male die 2 completely to form the product, a plurality of positioning blocks 5 used for positioning the product are arranged on the blank holder 3, the blank holder 3 can be ejected out by an ejector rod of an oil press, the pressure in the stretching process is adjusted through the pressure of the ejector rod, and therefore the quality of the product is guaranteed.

Further, the positioning block 5 is used for positioning a product.

Further, a mandril hole is formed in the lower die seat 4.

Furthermore, the blank holder 3 is arranged on the lower die holder 4 and sleeved on the periphery of the male die 2, can move up and down under the action of an ejector rod of the oil press, can bear the pressing force in the stretching process, and is uniform in pressure and smooth in material feeding.

Further, the female die 1 acts on the blank holder 3 in the downward movement process, and the formed product is clamped in the middle.

The working principle of the automobile part casting stretching die with high production efficiency is as follows: the blank holder 3 floats up under the action of an ejector rod of an oil press, the ejector rod has certain force, so that the blank holder 3 is higher than the male die 2, the material sheet is placed on the blank holder 3, and the material sheet is well adjusted and fixed by a positioning block 5 on the blank holder 3. The female die 1 starts to move downwards to contact the material sheet, so that the blank holder 3 of the female die is stressed, the female die 1 and the blank holder 3 clamp the material sheet to continue to move downwards, and the ejector rod has certain force to prevent the material sheet from wrinkling. The downward moving material sheet is contacted with the male die 2 and is formed, the female die 1 and the blank holder 3 are always in a stressed state in the process, and the material sheet moves to the bottom to enable the material sheet molded surface clamped between the female die 1 and the male die 2 to be completely matched with a product to be formed at one time and then taken out.

Compared with the prior art, the automobile part casting stretching die with high production efficiency can be formed by one-step stretching, scratches on the surface of a produced part are prevented, and the working efficiency is greatly improved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
